Answer:
True
Explanation:
Cofactor is a biological term used in describing a form of a non-protein chemical compound. It is highly required in the biological operation. It is in two types, the Coenzymes and Prosthetic groups.
While the Prosthetic groups are well connected to an enzyme, the coenzymes on the other hand are conected to an enzyme loosely.
Hence, it is TRUE that Cofactors for some enzymes are not considered prosthetic groups because they are loosely held during the course of the action
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
Sheeps possibly should be able to run quickly, to have a good sense of smell and to have quick reflexes.
These three sheeps are desirable for sheep as they enhance their survival capabilities. These traits are passed on to the new generation through reproduction.
Transpiration is the rate of the water vapour exhalation by the plant cells through its opening pores. The correct blanks are guard cells and closing.
<h3>What is the structure of plant cells regulating transpiration?</h3>
Plant cells have certain specialized cell organelles that help in maintaining the rate of the carbon dioxide and the water content in their cells.
Stomata of the plant cells are specialized organelles that maintain the water and rate of transpiration by the plants. They have guard cells surrounding them that regulates their opening and closing.
The guard cells of the stomata form pores of the stomatal opening. The opening and the closing of the pores are regulated by the bulge and the carbon and the water intake and outtake of the cell is maintained.
Therefore, option A. <u>guard cells</u> and <u>closing </u>are the correct blanks.
